How long can I fill my teeth after washing them?

It is recommended to fill the teeth after 1 week.

After tooth washing, the gums are prone to bleeding, and there is more gingival crevicular fluid, which leads to the loss of gingival filler when filling teeth. If there is a cavity near the gum, it is easy to be polluted when filling teeth, and the filling effect will be better after the gingival inflammation subsides. For dental caries on the occlusal surface, if the water separation is tight, the teeth can be filled immediately. Avoid irritating food within 1 week after filling teeth, and check regularly to prevent secondary dental caries.
